| 摘 要： | 等深流沉积是深水牵引流沉积中的一种重要类型，根据粒度特征，可将等深积岩划分为泥级，粉砂级，砂级和砾级等类型，它们可以组成特征的细－粗－细垂向沉积层序，从产状，成分，结构，沉积构造，垂向层序和与海平面变化的关系等方面总结了等深流沉积的若干鉴别标准以及其他类型深水沉积的区别。

| Abstract: | A contourite is an important type of deep water traction current deposits. Contourites are classified according to grain size and grain types into (1)mud size contourites, (2)silt size contourites, (3)sand size contourites, and(4)granule size contourites, etc. These contourites usually display a distinctive vertical succession of fine coarse fine. According to the occurrence, composition, texture, sedimentary structure, vertical succession of contourites and their relationship with the sea level,some discriminating features of contourites are summarized to distinguish them from other types of deep water deposits. |
